PHP文件POST类

最近学着写点PHP,写了个文件POST的类,可以很蛋疼地在服务器端POST文件到另一台服务器上……

 

<?php
    class SingleFileSender{
        
        private $headers=array();
        private $boundary="";
        private $postData="";
        
        /**
         * @param {Array} $url参数集
         *                 {String} path 
         *                 {String} host 
         *
*/
        private $urlParams=array();
        
        function __construct($url){
            $this->updateURLParams($url);
            $this->initHeaders();
        }
        
        /**
         * 设置发送的header
         * @param {String} $key
         * @param {String} $value
         
*/
        public function setHeader($key="",$value=""){
              $this->headers[$key]=$value;
        }
        
        /**
         * POST发送数据
         * @param {Array} $datas
         *                     array(
                                array(
                                      "postName"=>"pic",
                                      "fileName"=>"/data/a.text",
                                      "file"=>"file content",
                                    "type"=>"text/plain"
                                      ),
                                  array(
                                      "name"=>"text1",
                                      "value"=>"text1's content"
                                      )
                              ));
         *
*/
        public function post($datas=array()){
            $ret="";
            $this->updateBoundary();
            $postData=$this->getPostData($datas);

            $this->headers["Content-Type"]="multipart/form-data; boundary=".$this->boundary;
            $this->headers["Content-Length"]=strlen($postData);
            
            $sendContent = $this->getHeaderStr($this->headers)."\r\n".$postData;
            
            //echo $sendContent;
            
            $fp = fsockopen($this->urlParams["host"], 80, $errno$errstr, 30);
            
            if (!$fp) {
                $ret="$errstr ($errno)<br/>\n";
            } else {
                fwrite($fp$sendContent);
                while (!feof($fp)) {
                    $ret.=fgets($fp, 128);
                }
                fclose($fp);
            }
            
            return $ret;
        }
        
        /**
         * 初始化header
         *
         
*/
        private function initHeaders(){
            $this->headers["Accept"]="*/*";
            $this->headers["Connection"]="Keep-Alive";
            $this->headers["Host"]=$this->urlParams["host"];
        }
        
        /**
         * 更新boundary
         
*/
        private function updateBoundary(){
            $this->boundary="BOUNDARY".microtime(true)*10000;
        }
        
        /**
         * 获取要post的数据
         * @param {Array} $datas
         * @return {String} $ret
         
*/
        private function getPostData($datas=array()){
            $ret="";
            $fileData=array_shift($datas);
            
            $ret="--".$this->boundary."\r\n".
                    'Content-Disposition: form-data; name="'.$fileData["postName"].'"; filename="'.$fileData["fileName"]."\"\r\n".
                    "Content-Type: ".$fileData["type"]."\r\n\r\n".
                    $fileData["file"]."\r\n";
            
            foreach($datas as $k => $v){
                $ret.="--".$this->boundary."\r\n".
                    'Content-Disposition: form-data; name="'.$v["name"]."\"\r\n\r\n".
                    $v["value"]."\r\n";
            }
            
            $ret.="--".$this->boundary."--\r\n";
            
            return $ret;
        }
        
        /**
         * 更新URL参数
         * @param {String} $url
         
*/
        private function updateURLParams($url){
            if(preg_match('/^http\:\/\/([^\/]+)\/?(.*)/',$url,$rets)){
                $rets[1] && $this->urlParams["host"]=$rets[1];
                $rets[2] && $this->urlParams["path"]=$rets[2];
            }
        }
        
        /**
         * 将header数组转化为String
         * @param {Array} $headerArr
         * @return {String} $ret
         
*/
        private function getHeaderStr($headerArr=array()){
            $ret="POST /".$this->urlParams["path"]." HTTP/1.1\r\n";
            
            foreach($headerArr as $k=>$v){
                $ret.="$k$v\r\n";
            }
            
            return $ret;
        }
    }
?>

 

 

使用示例:

 

<?php
    include "SingleFileSender.php";
    
    $fileName="1.jpg";
    $handle = @fopen($fileName, "r");
    $file=fread($handle,filesize($fileName));
    fclose($handle);

    $sfs=new SingleFileSender("http://localhost/upload.php");

    $sfs->setHeader("Cookie","abc=123");

   
    echo $sfs->post(array(
            array(
                  "postName"=>"pic",
                  "fileName"=>$fileName,
                  "file"=>$file,
                  "type"=>"image/pjpeg"
                  ),
              array(
                  "name"=>"value1",
                  "value"=>"123456"
                  ),
              array(
                 "name"=>"value2",
                 "value"=>"abcdef")
          ));
?>

 

 

 说明,通过url实例化对象后,支持对其header的设置。

 post参数为array类型,

     第一个参数为文件数据,包括postName,fileName,file,type只个参数

    postName 可以让接收方知道传递的文件参数名称;

    fileName 为文件名;

    file 为文件的数据;

    type 为文件的MIMI类型名称。

 

  后面的参数可无限增加,为普通的post参数,以name和value的形式传入
